The question seems mostly to be within a quote block, but I can't tell whether it's a quote from somewhere (e.g. a textbook or past exam paper) or whether the user just randomly put quotes around the question for no reason.
edit: the quote block was edited in by someone other than the OP. I've now removed it.
If the former then it obviously should be closed according to the current policy. I don't think there's any room for debate there. The policy says that homework questions should show some effort, which clearly isn't the case here, with the question in its current form.
There is room for debate about whether it should be allowed by any future policy (honestly I'm on the fence about that), but since the new policy isn't in effect yet I'd say it should stay closed, at least until the user can reword it so it doesn't look like a verbatim quote from somewhere.
Of course, if this is just a case of "random quotation marks" then there's no problem except the formatting. In that case it's a conceptual question and the user has made some effort to specify it clearly, and it should be easy enough for the OP to edit so that it doesn't give the impression of being a copy-and-paste.
